I know this is a tall order but..... I'd be *most* appreciative if anyone would be willing to run a little experiment for me. Honestly, the only thing you would probably get out of it would be my appreciation and the knowledge that you helped someone out. I'd even be willing to throw a little something in. So, I'm looking for someone to load 2 demos and see if they are playable at a decent frame rate. The games (demos) are Call of Duty 4 and Unreal 3. If you are interested, I can send you dl links. Of course, the games could immediately be trashed and your system would never even know they were there. If the demos are indeed highly playable, I will be at the Apple Store the next day to pick up my 24" iMac.
